Available for download, Sacconi Strings Volume 1: 1st Violin from Spitfire Audio is a performance-oriented virtual instrument based on 17,512 samples of violin articulations geared towards string quartet and other chamber ensemble performances. The virtual instrument draws on the sampled material as you play on your keyboard, recreating your performance in a violin sound. Performed by Ben Hancox, first violin of the Sacconi Quartet, this volume covers the most essential string articulations within the chamber-music context including long notes, flautando, long & short harmonics, marcato, measured & unmeasured tremolo, pizzicato & Bartok pizzicato, col legno, major & minor trills, spiccato, and staccato. For the short articulations there is a stretch slider which enables you to stretch or shrink the sounds to the exact length you want.
The sounds are available in a choice six microphone perspectives and two microphone mixes that can be combined and blended for effectual shifts in focus and depth. For further sound customization there are sliders that modulate overall volume (called "expression"), vibrato intensity, and dynamics. The library is sampled with multiple, slightly varying versions of each sound, known as round robins. As opposed to having one sample per note, round robin sampling stores multiple samples per note, so that the same sample is never triggered repeatedly. This eliminates the "machine-gun" effect caused by repeated triggering of the same sample and gives your virtual performance a lifelike feel. Sacconi String Quartet captures the beautiful acoustics of the Wigmore Hall in London, where it was recorded.
